Find and Replace
Whether you need to swap a misspelled name across an entire document, update outdated terminology, or strip out unwanted patterns, our free Find and Replace tool handles it all in your browser. Type a search term, specify what to replace it with, and see every match highlighted in the preview before committing. Toggle case-sensitive matching to distinguish between "Apple" and "apple", enable whole-word mode to avoid partial matches, or switch to regex mode for advanced pattern matching with full regular expression support. The tool displays the total number of replacements made so you can verify the scope of your changes. It works beautifully alongside the Remove Extra Spaces tool when replacements leave behind double spaces, and pairs well with the Case Converter for standardizing letter case after bulk edits. Everything runs client-side with zero data collection, making it safe for confidential content, legal documents, and private notes.

Frequently Asked Questions
- What does regex mode do?
- Regex mode treats the find field as a regular expression pattern rather than plain text. This lets you use special syntax like \d+ to match numbers, .* to match any characters, or [A-Z] to match uppercase letters. It is a powerful option for advanced search patterns.
- How does whole word matching work?
- Whole word matching adds word boundary markers around your search term so it only matches when the term appears as a standalone word. For example, searching for 'cat' with whole word enabled will not match 'category' or 'concatenate'.
- Can I replace with an empty string to delete matches?
- Yes. Leave the 'Replace with' field empty and every match will be deleted from the text. This is a quick way to strip out unwanted words or patterns.
- Is the replacement applied globally or only to the first match?
- All matches are replaced at once. The tool uses the global flag by default so every occurrence of the search term in the text is replaced simultaneously.
- What happens if my regex is invalid?
- If the regex pattern is invalid, the tool gracefully returns the original text unchanged and shows zero matches. No error dialog or crash will occur.
